; Application filed June 24, 1925. Serial no. 39,202.

My present invention is, in a measure, 00- related to that described in my concurrent application Serial No. 34,773 filed June 4th,

1925; in that the object is to afford substantial and effective locking means for doors and analogous closures, said locking means being not only "practically burglar proof in character, but also embodying alarm.

mechanism whereby ample notice is assured inthe event of any attempt at tampering with the door orlocking means. My said concurrent application relates, hoW-' ever,Fmore particularly to door mortise lock mechanism, whereas the improvements hereinset forth aredesigned primarily for embodiment in an interior or rim lock for posslble use, either .alone, or in con1unct1on v with door mortiselocks generally, other than my aforesaid specific .mortise lock,'this invention "cons sting 1n the specific combination, construction andiarrangement of com v ponent parts and appurtenances described and claimed, whereby these and other advantageous results are attained substantially as hereinafter explained.

' In theaocompanylng drawings I illustrate a practical embodiment of the essential fea- ,tures of my invention as incorporated in what'may be designated as a rim or exterior auxiliary lock as applied to the inner side of afdoor in conjunction with an outside latch" key lock of the Yale or equivalent type although I do not limit myself to the identical form of component parts herein shown 7 by way of exeinpl fication, s nce changes may be made in minor details, and

- equivalent inechanical' exp'edients resorted to with like results, and without departing from the spirit and intent of my invention in this respect. r

As indicated in Figs. 1, 2, 5 and 6, of the drawings, my rim lock, so called, is applied to the inner side of a door. D, or analogous closure, J, J, representing adjacent portions ofthe j'amb or frame work thereof,and F,

the floor, K, is a latch keylock of any well known type positionedin the door D, and

is in alignment and, en agement with a slot a, formed for the purpose in the hub of the key shift arm A, as and for the purpose hereinafter set forth, V p

'The'operative parts of mylock mechanism areinclosed in a box casing B, and

B, bein'g screwed, as at b, b, b, b, to the door D. and the cover B, to the boxB, as

A horizontally slidable bolt plates, is supported'on thebackor base plate 6, of the casing box 13, byxanyssuitable means, as

by a stud b insaid baseplate b, extending through a longitudinal slot 8, formed for the purpose in the slide plate S, and by the engagement of its twin horizontal jamb bolt-s1, I, with bearing apertures 79*, 6*, in

the guide flange Z2 which forms one end wall of the casing box B,said twin ja-mb bolts 1,1, being adapted for locking ,engagement, when shot with the door-D, in closed position, with the jamb socket plate J which is rigidly secured to the vertical jamb J, of the door in a position coincident with said guide flange 6 of the casing box B, whenthe door is closed, as will be obvious by reference more particularly to Figs. 1, 2, and 4, of the drawings. 1 Said horizontal'twin jamb bolts 1, 1, ar rigidly mounted, as by screws 2', 2', on a bracket plate S", which is in turn rigidly screwed to the end abutment s, of the slidable bolt plate S. The latter is formed at its otherv extremity with centrally con vergent slots s for engagement, respectively, with fulcrum studs on the inner ends of the supplementary vertical brace bolts UandL. i n

Thus a stud u, on the lower extremity of the upper supplementary brace bolt U, protrudes into the upper inclined slot 8 of the slide plate S, said upper supplementary brace bolt U, extending through the top flange of the casing box B,and to a guide cap (Z, on the top of the door D, as shown in Fig. 1, of the drawings, said guide-cap d, When the door is closed, being in alignment with the socket plate j, on the upper member of the door jamb J, so that when said supplementarybrace bolt U, is ,s hotfu ward, it will engage said socket plate j, I

slot 8 of the slide plate S, saidlower supplementary brace bolt L, extending through the lower side flange of the casing box B, and to a guide cap d, on the bottomof the door D," also as shown in said Fig. 1, of the drawings, said guidecap cl, when the door is closed, being in alignment with the mortise plate and socket f, countersunk in the floor F,so that when thesaid supplementary lower brace bolt L, is shot downward it will engage with said mortise plate and-socket thereby reinforcing and securing the lower portion of the door against external pressure.

. Thus ll andL, are adapted to pos1t1vely secure the door D, in closed and bolted position inde endent of alt-hou' 'h co-related to the horizontal twin jamb bolts 1, l, and intervening mechanism. In the accompanying drawings these supplementary brace bolts U andL, are shown-as positioned and operating vertically, although they may be otherwise positioned and operated with substantially like results in adapting them to special requirements of use, as may be found: most expedient. V

A ward lockxplate W, is rigidly attached by means of screws to, w, to female-threaded bosses 7), 6 on the base plate 6, of the casing 13, said bosses'b 6 being protuberant from said base plate Z), a sufiicient distance to position the ward loclrplate-W, beyond the plane of the bolt slide plate S. In this connection it maybe explained that the nuts 70, 7c, engage the inner endsof the bolts [5 71: by which the. exterior latch lock K, is secured in position on and in the door D, as will be understood by reference more particularly to Figs. 2, 3, 4 and v6, of the drawings, the said bolts I6 [0 extending through apertures I), 6, formed for the purpose int he aforesaid base plateb, of the casing 7 l3; 7 V r '72, 25, is the aperture in the base plate 6, of the casing B, through which the hub '06, of the key-actuated shift arm A, protrudes, the outer extremity of said hub a,

being supported in the central circular bear:

ing aperture to, of the ward lock plate I,

as'shown more particularly in Fig. 2,- of the drawings, inconnection with Fig. .12, thereof. The said bearing aperture w,in the ward lock plate W, also aitords support for the inner end of the hub h, of the hand shift arm lithe outer extremity of said hub 71, being seated and supported in a bearing aperture 6*, formed for the purpose in they the two supplementary bracejbolts casing cover B, as shown in Fig. 2, of the drawings. A manipulatlve knob-or handle being provided at its upper extremity with a pin 6, which protrudes into the slot h, in hand shift arm H. I

The lower end of the spring latchE, is formed with a recess 6', (Fig. 14:) for the reception of one end of a retractile spring 6 the coil of which is supported on the shank of ascrew 8, engagingwith a female screw thread 8 (Fig. 18) formed for the purpose in the slidable bolt'plate S, the other end of said retractile spring e bearing against the abutments, on said slidable bolt plate S, as shown in Figs. 3, 4 and 7, of the drawings. constantly to thrust the latch E, upward with its upper extremity in engagement with the stationary ward plate 7, and normally in one or the other of the wards 10 w Thespring latch E, may be depressed against the resistance of the retractile spring e ,'by means of either the hand shift arm H, or the key-actuated shift armA, as the case may be. That is to say, as either is shifted from right to left, or vice versa, the arc of the circle traversed by the extremity of each as it passes beyond the medial line coincident with the axes of support, will push the said spring latch E, downward sufficiently to clear either of the wards 10 co of v the stationary plate and shift the slidable bolt plate S, in one direction or the other,

the reciprocative movement of the bolt plate S, thusprovided for being attained in'the one case by reason of the contactual engagement of the end of the hand shift arm 'H,

.with the push shoulder 0 on the front of the spring latch E, and with the lateral shoulders s .9 on the slidable bolt plate S, and in the other case by reason of the contactual engagement of the end of the key-actuated shift arm A, with the push shoulder 6 on the rearside .of sa'id spring latch E, and withthe side walls of the slot .9", in theslidable bolt plate S, as will be understood by reference more particularlyto Figs. 18, 20, 26 and 27, of the drawings.

The alarm-actuating rock lever B, is fulcrumed on the shank of a screw 1", the threaded end of which engages with a female threaded boss 5 on the base plate 6, of the casing box 13, the upper extremity of said alarmactuating rock lever B, being formed with a push finger 7", which is positioned in This retractile spring 6 tends contactual relationship (see Fig. tothe release means a, of'the otherwisefautomatic alarm' sounding device N, thelatter being. of a noise producingspring-operated type. well known commercially, for any equivalent thereof adapted'to the purpose. v 1 The saidalarm-actuating rock lever B, is also formed with a lateral push arm1' the free end of which, when the bolts are shot, as in Figs. 4 and 7 ,of the drawings, contacts with the protuberant lower portion e of the rock lever. Hence, under the conditions shown particularly in Fig. 4, any attempt to force back either or any of'the aforsaid bolts by means other than the manipulation lock mechanism herein designated, will result in pressure exerted upon and through the slidable bolt plate S, and by it to and-through the spring latch E, to cause the latter to rock the alarm-actuating lever R, sufiiciently to contact with and press against the alarm releasing means at, thus insuring the setting off of the alarm, and fustrating' surreptitious entrance through the door or other closure thus. protected.

This action ofback pressure on the slidable illustrated in Fig. 7, taken-in conjunction with Figs. 1 and 4, of the drawings:

But this operative co-relation of actuating rock lever B, and spring latchE, under the circumstances of unlawful tampering with the bolt means, as above intimat- .ed does not interfere with the legitimate function and operation of the lock mechanism, because, when the spring latch E, is depressed by either the hand shift arm H, or by the key-actuated shift arm A, the protuberant lower portion 6*, of the spring latch E, is below the push arm w, of said alarm actuating rock lever B, and hence the'slidable bolt plate S, may be freely reciprocated by either the key actuated shift arm A, or the hand shift H, without interference with the alarm sounding means.
